Jawaban:
a. S' = - 6 cm
b. M = 2 kali
Penjelasan:
diketahui:
S = 3 cm
F = 6 cm karena cermin cekunɡ, maka jarak fokus cermin bernilai positif
ditanya:
a. S'
b. M
jawab:
a. 1/F = 1/S + 1/S'
1/S' = 1/F − 1/S
1/S' = 1/6 - 1/3
1/S' = 1/6 - 2/6
1/S' = -1/6
S' = -6 cm
b. M = ∣ S'/S ∣
M = ∣ -6/3 ∣
M = 2 kali
